Patented Aug. 91910 STEAMER.

Application filed February 3, 1910. Serial No. 541,876."

1'0 all whom it may concern:

Be it known that I, FRANCIS J. Aipnnnci rr, a citizen. of the UnitedStates of America, residing at Pittsburg. in the county of Alleheuy andState of Pennsylvania, have iniented certain new and useful improvements in Steamers. of which the Following is a specification. referencebeing hail therein to the accompanyina drawing.

This ii'iveution more particularly to that type of steamer used "forgenerating steam adapted to be. injected in a proofing box or orenduring the raising of bread and the baking thereof.

The primary object of my invention is to provide steam-generatingapparatus that can be safely and easily operated to quickly producesteam from fresh water. thus avoiding the impurities in steam that isgone atcd .trom water that has stood for some time, as

in large boilers.

Another object of the invention is to provide a portable steamer with awater reservoir positioned to autonuitically feed water to a. coiladapted to be heated by a tianle either from a gas burner or from a coalfire.

A further object of the invention is to provide a steamer of the abovetype with means as will be hereinafter set forth for controlling thesupply of nter to a steam generating coil.

A further object of the invention is to provide a steamer that is simplein construe-- tio'n inexpensive to manufacture and highly efficient forthe purposes for which it is intended.

With these and such other objects in view as may hereinafter appear, theinvention consists of the novel construction combination. and arangement of parts to be here inatter specifically described and thenclaimed.

Reference will now be had to the drawing, wherein Figure 1 is a verticalsectional view of a rnan'crs J. ALBRECHT, or rrr'rsBUnG,rnnnsyiivalviin,

metal having the edges thereof overlap} I p and connected. as at 2.Thecylindrical shell has the lower end thereof provided with legsladapted to slipport tlie an elevated position above a gas-burner butwhen thesteanier is to be used" nection with a coal tire. the'lowerend'o'f shell 1 is provided with a flaring ha;

best shown in Fin. 2 of the drawing;adapt (m ed to support the shell 1upon the "c the lir'c. The upper end of thcsliel provided with aninwardly projecting fl and pivotally connected to said lug rivet or pin(3 is a lidT adapted to clo upper end of the shell. This l v 'videdadjacentto ondedge with aii open M 8 and with a slot 9, and theobject'of both will presently appear. i 3 The shell 1 is provided with:inintgrior lining); of asbestos 10 or otherfireproof n; terial. and saidshell inte'rmediate"the I thereof is provided witlr inwari'llyiprojetttt ing brackets 11 adapted to supported 6 or reservoir 12containiiugwatt-1*l2 v Pl'1e80' tank or reservoir 12 is cyliudi' icala'nd ol ll less diameter than the shell 1. thc' tank reservoir being;supported cccentricallv wit in the shell .1 to provide a space '12 bside of the shell, bcti'vcen the innersideof 35 the shell and the outersideot theQtluik' reservoir 12.

Extending into the bottom of the tankor reservoir 12 is a pipe 14.-having' the upper end thereot provided with an ell )ow"'l5 "co'nnectedby a pipe 16 to an elbow 17, the lower end of said'elbo'w extendingdnt'oproximity to the bottom of the tank or reser voir 12. In the elbow 17 ismounted ninth-L ing 18 having a central opening 19. Adapted to closethis opening is a gravity valve or spherical body 20, the object ofwhich will presently appear. The lower end of the pipe 14. is connectedby an elbow 21 to the lower convolution 22 ot' a coiled tube 23 locatedin the shell 1, between the lower end of the tank or reservoir 19 andthe lower end of the shell. The uppermost convolution 24- ot the coil oftubing'is connected by an elbow 25 to a stand pipe 26, said pipeextending upwardly.betwcen the shell 1. and the tank or reservoir 12.The pipe is adapted to extend through the slot 9 of the lid 7, the slot9 being disposed at an angle to permit of the lid being swung openwithout interfering with the stand pipe 26.

Mounted upon the upper end of the stand als of pipe 26 is a valve body27 having a hot 1 medium of this valve that the Water'within waterOutlet pipe 28 located above the open- I ing 8 of the lid 7, said valvebody also having an elbow 29 connecting with a steam outlet pipe' 30. Inthe valve body 27 is a valve plug 31 having ports 32, 33, and 34. Thevalve plug is retained within the valve body by a washer 35 and a nut 36at one end of the plug and at the opposite end thereof is provided witha handle or crank 37 The ports 32 and 34 are adapted to establishcommunication between the stand pipe 26 and the steam outlet pipe 30,while the ports 33 and 34 are adapted to establish communication betweenthe stand pipe 26 and the elbow 29 with the side of the valve ph gclosing the hot Water outlet pipe 28.

hen gas is utilized as a beating medium, pieces of wire 35 or other heatretaining and conducting materlal can be placed centrally of theconvolutions of the coil oftubing, whereby the heat from the as burnerwill be retained and properly disseminated relatively to the coil oftubing. The heat retaining and conducting material can be dispensed withwhen a coal fire" is used. p

When the tank or reservoir 12 is filled With Water or nearly so, theWater raises the gravity valve 20, fillsthe coil of tubing 23 andassumes a level Within the stand pipe26 corresponding to the level ofthe Water With- I Y in the tank or reservoir 12. When the coil of tubingis subjected to the action of a flame, either gas or coal, the waterwithin 20 will then open and allow a quantity of Water to enter thecoil, and it is through the the tank is automatically fed to the coil.

The shell 1 is provided with a suitable bail 40, whereby the steamer canbe easily carried-from one location to another, for instance, from aproofing boXto an oven. I

I attach considerable importance to the fact that the reservoir or tank12 can be easily cleaned. and from'time to time filled with pure water,consequently the steam generated from the water will contain a minimumamount of impurities and thereby prevent the steam from injuring thebread with which it contacts.

While in the drawing there are illustrated the preferred embodiments ofmy invention, it 1S to be understood that thestructural withoutdeparting from the spirit and scope of the invention.

, elements thereof can be varied or changed Having now described myinvention whatof water from the coils to the tank, the upper end of saidtubing provided with a vertical stand pipe located within the casing andprojecting beyond the top thereof, a three-way valve mounted upon theend there of, a return pipe connectin with said valve directing a returnof the uid to said tank through said apertur-ed cover, a steam outletpipe connected to said valve, and a heating means arranged below saidtubing, substantially as described.

in testimony whereof I aflix my signature in the presence of twowitnesses.
